Simple Configuration: Media Gateway to Access PSTN Networks
GXW-410x can be configured to work with any leading SIP server, for a pure media gateway to access
PSTN networks. In such applications, the user only needs to configure GXW-410xgateway Stage Dialing
field and Sip Server field.
For a simple set-up, users only need to configure a SIP server field for default SIP Profile 1. This field
should be configured to point to the SIP server to be used with the GXW-410x.
For advanced applications, the user is required to choose at least one SIP server field from the SIP
profiles and one stage dialing under system Channel configuration table. On SIP server sides, the SIP
server must be configured to forward user PSTN calls to the GXW-410x.
Please be aware that by default, the system uses North American PSTN settings and TWO STAGE
dialing to access PSTN networks for VOIP to PSTN calls and PSTN to VOIP calls. Two stage dialing
means the end-user will hear dial-tone twice. First dial-tone is used to let users to input destination
number in the same network of the calling networks. Second dial-tone is used to let users to input final
destination number.
The GXW-410x also supports ONE STAGE dialing, which means users only need to input one final PSTN
number when first dial-tone is heard for calls from VOIP to PSTN. This requires configuring both SIP
server and GXW-410x to one stage dialing (see last section of quick guide and user manual for one stage
dialing). For one stage PSTN to VOIP calls, user needs to configure off-hook auto dial field (see last
section on sample configuration
Extensive Configuration: Media Gateway Configuration for Multiple Users
The GXW-410x can be configured to work with a variety of SIP server features and traditional PBX on
PSTN networks, with a different SIP server on each physical port. Each port may have its own voice
setting, dialing settings, PSTN termination setting, and DTMF transmission settings.
Off-hook Auto Dial
The FXO interface currently does not support direct inward dialing (DID). The GXW-410x implements an
off-hook auto dial feature for each physical port. Configure off-hook auto dial to forward PSTN incoming
call to a specific SIP number, call center or hunt group.
Sample Configurations - IP PBX Peers with GXW-410x
There are 2 methods to configure GXW to work with IP PBX:
1) Configure GXW with SIP Accounts in IP PBX, this will enable you to put GXW behind a
NAT/Firewall.
2) Configure GXW without SIP Accounts in IP PBX, this makes GXW function as a PEER gateway.
Please see the Quick Install Guide at www.grandstream.com.
Note: In regions other than North American, the user is also required to configure call progress tones and
PSTN line termination fields. Check with local PSTN service carriers on values service providers use on
the lines. If service provider doesn't provide those values and users don't know what the correct values
are, please use the default values. Contact product support if you still have questions about configuring
your GXW-410x.
